六氟苯与PhSeNa在二甲基甲酰胺（DMF）中反应得到1,4-二（苯基硒）苯3和1,2,4,5-四（苯基硒）苯4，而不是报道的六（苯基硒）苯1。六溴苯与PhSeNa在六甲基磷酸三酰胺（HMPA）中反应得到1,4-二- 6,1,2,4,5 -四-7和六（苯基硒）苯1。通过x射线晶体学分析确定了产物的结构。
Reactions of hexafluorobenzene with PhSeNa in dimethylformamide (DMF) afforded 1,4-bis(phenylseleno)benzene 3 and 1,2,4,5-tetrakis(phenylseleno)benzene 4, instead of the reported product, hexakis(phenylseleno) benzene 1. Reactions of hexabromobenzene with PhSeNa in hexamethylphosphoric triamide (HMPA) afforded 1,4-bis-6, 1,2,4,5-tetrakis-7 and hexakis(phenylseleno)benzene 1. The structures of the products were established by X-ray crystallographic analysis.
